unable to create Data extension from existing fields of other data extension

Question

Hi i am unable to create a dynamic data extension from the existing data extension fields. I am using the following code to get that

<script runat="server">
Platform.Load("core","1.2");
var dummyDE = DataExtension.Init("80c489be-20f3-448b-b683-2b098cae20dc");
var fields = dummyDE.Fields.Retrieve();
var DE = "MyDataExtension1", FolderName = "Amit";
var FolderAttributes = Folder.Retrieve({
  Property: "Name",
  SimpleOperator: "equals",
  Value: FolderName
});
var FolderID = FolderAttributes[0].ID;  
var obj = {
  "CustomerKey" :"XYZ",
  "Name": DE,
  "CategoryID": FolderID,
  "Fields": fields
}
var Status = DataExtension.Add(obj);
</script>

The only issue with your code is that you are not referencing a valid Core Library version. Try:

Platform.Load("core","1.1.1");

The only other thing to be aware of is, if you have multiple folders named "Amit", then the retrieve function will return multiple objects in the array. Not specifying the exact folder you need may result in the DE being created in a different folder to the one you were expecting.
